Thanks for all your comments ! it is nice to read you all here and also to see what is new by the others ceramists : it is encouraging to go on and to drink tea too. I started a reaserch on "white" with differents textures : mat, brillant, rough, bubble, eith nuances from white -cream-beige to grey and so on. It is just the beginnig . One here :

I am working on a "serie" concept : i make bowls and glaze them and choose the number of that "série" . And then I select the one that i am really satisfied with.The other of that "serie " are just broken. Here, for exemple, I make 4 macha bowls with tenmoku and ohata glazes. We can see that ther is oil spot and some metallisation of the glaze.

First one :

Second one :

And the 2 others are eliminated.

Just here this is a very little "série" , with only 4 bowls at the beginning.The purpose of that is to make some collection bowls that will be considerated like little sculptures . I am at the beginning of that process . But I do also others bowls as before !
